Value Collection R63062442 Button Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R63062442 is a button head socket cap screw designed for applications requiring a low-profile fastening solution with a clean finished appearance. It features a 5/16-18 UNC thread and measures 1-1/4 inches in length under the head. Driven by a 3/16-inch hex socket, it is manufactured from 18-8 stainless steel with a bright, uncoated finish. This combination of alloy grade and thread standard meets ANSI/ASME B18.3 requirements, making it a reliable choice for maintenance, fabrication, and equipment assembly work performed by machinists, millwrights, plumbers, and general contractors.

This screw is suited for light to medium-duty fastening in applications where corrosion resistance matters and head clearance is limited. The button head profile sits lower than a standard cap screw head, making it a practical fit for panels, covers, brackets, and enclosures in both indoor and outdoor environments. The 18-8 stainless steel construction handles exposure to moisture and mild chemicals without surface degradation. It is commonly used in HVAC equipment assembly, electrical enclosure fabrication, plumbing fixture mounting, and general structural hardware applications.

Key Features

• Low-profile button head allows installation in space-restricted or flush-mount applications
• 18-8 stainless steel construction provides corrosion resistance in wet or humid environments
• 3/16-inch hex socket drive for positive torque engagement with standard Allen keys or hex bits
• 5/16-18 UNC right-hand thread with Class 3A fit for consistent engagement and reduced slop
• Bright, uncoated finish — no coating thickness to account for in tight tolerance applications
• Meets ANSI/ASME B18.3 fastener standard for dimensional conformance

Compatibility

Designed as a standard-dimension 5/16-18 UNC button socket cap screw conforming to ANSI/ASME B18.3, suitable for use wherever this thread size and head style are specified.

Installation Notes

Install using a 3/16-inch hex key or hex bit driver. Ensure mating threads are clean and free of debris before driving to avoid galling, which is a known risk when threading stainless steel fasteners. Do not exceed recommended torque for 5/16-18 stainless hardware as specified by the equipment manufacturer or applicable structural guidelines. Always verify thread engagement depth meets the minimum required by the joint design before final torque.
